UniBeast has been updated to 1.5 for Lion and OS X Mountain Lion. We've broken UniBeast out into two versions based on operating system. UniBeast - Lion is the functional equivalent of previous versions of UniBeast. UniBeast - Mountain Lion is the new version that supports 10.8 only.

The latest version is available for download at tonymacx86.com/downloads.If this utility has helped you, please consider a contribution to support further UniBeast development. Thanks in advance, and enjoy!

After a year of development, the day is finally here- we've updated the entire website. It's a brand new tonymacx86.com designed by our team and powered by vBulletin. There are a ton of amazing new user features we'll be rolling out gradually, literally too many to list.

The site has been completely redesigned! As part of the re-activation process, all users are required to reset their password. Follow this link and enter your email address, and you will be emailed directions to reset your password. If that link doesn't work, go to the forum homepage and reset your password manually.

Going forward we'll be writing articles and blogging directly on the new site, and as a new launch feature we'll start promoting great user threads to articles. This way every user will be able to write for the community- your custom build could end up on the front page of the site!

Hope you like it as much as we do! If you need anything, the old site is here. Please bear with us if there are a few things that don't work quite the same way yet. We're working on it as hard as we can.

Off and on over the past year or so, we've been collaborating, designing, testing and setting up a new more modern website and forum. We're happy to announce that the resulting new tonymacx86.com will be launching this Sunday!

We will be importing all current forums, posts, and users and shouldn't be going offline at all during the transition. However, the existing forum will be read-only for 7-8 hours.

Today MacMan updated Chimera to version 1.11. We've fixed the experimental Ivy Bridge HD 4000 graphics card support. Using the available HD 4000 drivers can be difficult, but we anticipate that updated Mac OS X 10.7.5 or 10.8 graphics drivers will make things much simpler. This is a GraphicsEnabler fix, and NO additional changes should be needed for HD 4000 support. This new version will be included in the next MultiBeast and UniBeast releases.

Apple has provided a concise rundown of how to update to Mountain Lion on day one here. The system requirements are the same for CustoMac Builds. To proceed with a retail installation, you absolutely need the following.

Intel Core 2 or above, 64 bit CPU

A computer running the latest version of Mac OS X Lion (10.7.x) or Snow Leopard (10.6.6+)

However, this time around there is a big change, as Mountain Lion is a 64-bit only Operating System. This means that there is no support for 32-bit only CPUs or 32-bit kexts. You will not be able to use the "arch=i386" boot flag to access 32-bit kernel and kexts mode. Some legacy 3rd party audio and wifi drivers may not work, and many older graphics drivers have been eliminated. If you want to check that you're currently using 64-bit kexts, this information can be viewed in System Profiler. Click on the Apple > About this Mac > More Info > System Info, click on Software. If the 64-bit Kernel and Extensions says Yes, you are clear to update.

Recommended Best Practices

When performing any full operating system upgrade, unexpected things can occur. To avoid data loss, these best practices should be adhered to. This upgrade should be a breeze, but if things do go wrong, you can always go back to your working Lion installation.
